Tighten the wing knob securely to hold the desired deflector adjustment once the desired position have been achieved. To engage the auger and start throwing snow, hold the auger clutch against the handle. AUGER & SCRAPER BLADE When engaged, the auger rotates and draws snow into the auger housing and throws it out the discharge chute. Rubber paddles on the auger also aid in propelling the snow thrower as they come in contact with the pavement. During initial break-in period of the auger, it is normal for the auger to build up excessive heat if not operated in the snow. Do not operate without snow or water for lubricating the auger. This will cause excessive heat build up in the auger which could cause damage to the auger and scraper blade. The scraper blade maintains contact with the pavement as the snow thrower is propelled, allowing snow close to the pavement s surface to be discharged. The auger and the scraper blade are subject to wear and damage. They should be checked periodically. Adjust or replace when necessary. Figure 7a During initial operation there may be wear between performance, both snow throwing and driving, occurs when there is zero clearance between these two parts. Know Your Machine 12

14 CHOKE SCRAPER BLADE Engage choke by rotating lever to CLOSED position whenever you are starting a cold engine. As engine warms up, gradually rotate the choke to the OPEN position. Do not use choke to start a warm engine. When the snow thrower is on a level surface the wheels, scraper blade, and auger should all contact the surface. If the scraper blade is adjusted too high, snow may blow under the housing. If the scraper does not self-propel, the scraper blade may be too low and needs to be adjusted. On new snow throwers with a new scraper blade installed, the auger may be slightly off the ground. Never use choke to stop engine. Follow these steps to adjust the scraper blade: PRIMER Press the primer to pump additional fuel from the carburetor to the cylinder for improved cold weather starting. Firmly push in the primer with your thumb, holding the primer in for a second before releasing it each time. 1. Run the snow thrower until the fuel tank is empty. 2. Pull the recoil starter handle until resistance is felt. Then tip the snow thrower back until it rest on the handle. screws which secure the scraper blade to housing. Move the scraper blade to the desired position and retighten the nuts and screws securely. Remove your glove when you push in the primer so that air can not escape from the primer hole. 10 mm Do not use the primer if the engine has been running and is hot. Excessive priming may ood the engine and prevent it from starting. RECOIL STARTER The recoil starter is on the back side of the engine. Pull the recoil starter handle to start the engine. SAFETY IGNITION SWITCH Insert the safety ignition key for engine to start and run. To stop the engine, remove the key. Figure 8 4. Tip the snow thrower back to the operating position and pull the starter handle a few times to plug and pull the handle several times to ensure that any oil trapped in the head is removed. Oil may come out of the spark plug hole when it is removed and the starter handle is pulled. 6. Inspect the spark plug. If it is wet, clean off any oil before re-installing. 13 Know Your Machine

15 Single-Stage Snow Blower» Operator s Manual AUGER CLUTCH The auger will not turn unless the auger clutch is engaged. The auger must stop within 5 seconds after the auger clutch is released. 1 The clutch cable must contain some slack when you disengage the clutch lever for the auger to stop properly. If the auger no longer turns when the auger clutch is engaged or if the belt slips under load, the auger cable or belt may have stretched. This can be compensated for by adjusting the auger clutch cable. The upper hole in auger clutch lever provides for an quick adjustment method. To adjust, unhook and move the clutch cable to the upper position. Insert the cable from the outside. 2 Figure 9b Spring Cover Spring Hook Z-bend Adjuster link 1. Slide up the spring cover and unhook the spring from the adjuster link. You can pull up the adjuster link and cable to make unhooking the spring easier. 2. Move the Z-bend to a higher or lower hole on the adjuster link as needed to obtain proper auger clutch adjustment. Lower Hole Upper Hole 3. Hook the spring to the adjuster link and slide the spring cover over the adjuster link. Figure 9a The cable adjuster link found under the spring cover provides further adjustment options if required. Test the snow thrower to see if there is a noticeable difference. If after the adjustment to the control cable the auger still hesitates when rotating, replace the auger belt. Know Your Machine 14

16 OPERATION STARTING AND STOPPING THE ENGINE WARM START Before starting the engine, check engine oil level and ensure the engine is maintained as described in the Engine Manual with the snow thrower. COLD START RECOIL STARTER 1. Be sure fuel shutoff valve is in the OPEN position. 2. Place ON / OFF switch in ON position. 3. Rotate choke control to CLOSED position. 4. Push the primer 2 or 3 times. When temperature is below 15 F (-25 C), additional priming may be needed. When temperature is above 50 F (10 C), priming is not necessary. Over priming may cause flooding, preventing the a few minutes before attempting to start and do not push the primer. 5. Grasp recoil starter handle and pull rope out slowly until it pulls harder. Let rope rewind slowly. 6. Pull rope with a rapid continuous full arm stroke. Do not allow starter rope to snap back. 7. Repeat steps 5 and 6 until engine starts. 8. When the engine starts, release the recoil starter handle and slowly move the choke control to the OPEN position. position and do not prime the engine prior to starting. Allow the engine to warm up for a few minutes, engine will not develop full power until it has reached normal operating temperature. In snowy and cold conditions, some controls and when trying to operate frozen controls. If you have difficulty operating any control or part, start the engine and let is run for a few minutes. SNOW BLOWING TIPS it falls. The best time to remove snow is the early morning. At this time and warming temperatures. 15 Operation Slightly overlap each successive path to ensure all snow will be removed. For large areas, start in the middle and throw snow to each side, so snow is not cleared more than once. overlapping previous path and move slowly. Throw snow downwind whenever possible. Keep engine clean and clear of snow during use. This will help air After snow-throwing is completed, let the engine run for a few minutes to help dry off the moisture on the engine and prevent moving parts from freezing. Engage the auger to clear any remaining snow from inside the housing. Rotate the discharge chute to prevent it from freezing. Stop the engine, wait for all moving parts to stop, and remove all ice and snow from the snow thrower. With the engine off, pull the recoil starter handle several times to prevent the recoil starter from freezing up. UNCLOGGING DISCHARGE CHUTE Never use your hands to clear a clogged discharge chute. Shut off engine and remain behind handle until all moving parts have stopped before unclogging. 1. Shut off the engine. 2. Wait 10 seconds to be sure the auger has stopped rotating. 3. Always use a clean-out tool or stick at least 16 (400mm) long, not your hands. SELF-PROPELLED OPERATION Tip the handle forward slightly to allow the rubber paddles on the auger to contact the pavement and propel the snow thrower forward. Pushing downward on the handle will raise the auger off the ground and stop forward motion. Excessive upward pressure on the handle will result in premature wear on the rubber auger paddles. TRANSPORTATION Always shut off engine, remove key, and close fuel shutoff valve when transporting unit on a truck or trailer. Do not transport machine while engine is running. Never pick up the machine by the auger handle. Secure unit chassis to transport vehicle. Never secure from rods or linkages that could be damaged.
